This means that the Xeon CPUs from the Mac Pro are far too weak to properly supply data to the RX 480 GPU. Although the RX 480 has some much better frame rates, the variation of FPS was very high. I took one of the RX 480's and placed it into the Mac Pro as per a tutorial.Īs you can see, there are some very strange results here.

I have a second gaming PC on which I run an Oculus Rift running two MSI Rumor RX 480 4GB. So instead of going "big" with the NVIDIA GPU, I pivoted to go "medium" with an AMD RX 480. This GPU is also not supported on macOS, but at this point I figured I'd try to exhaust all of my options.

The AMD RX 480 is a recent generation mid-range GPU that is good for 1080p gaming and entry-level VR. After a bit more googling, I came across an excellent tutorial on installing an AMD RX 480. I made further google searches and there were a few things I could try, but, frankly, I think that this Mac Pro is just too old to properly power the 1080 ti. I powered off the Mac Pro and put the old GPU back in and it booted up without issue. The Mac Pro powered on, but it didn't make the familiar Mac "bing" on start up. I plugged in the two 6-pin power cables anyway and closed the side panel and fired up the Mac Pro and I waited for the login screen… and waited. No matter! It's only missing a measly 25W.

Each 6-pin power cable provides 75W plus the PCI connector bus provides another 75W for a total of 225W.

Plug in the 6-pin and the 8-pin power cables.Įxcept the 2009 Mac Pro doesn't have an 8-pin power cable.

Unscrew the expansion card retainer plate.

Disconnect the 6-pin power cable from the old GPU.

I shut down the Mac Pro and proceeded with the hardware installation.

With my new macOS Sierra freshly installed, I was able to successfully install the NVIDIA beta drivers without issue. If the computer restarts when you press the SYS_RST switch but not from a cold start, the power supply may need to be replaced.Install the drivers and swap in the GPU.

If the computer boots after you press the SYS_RST switch, try shutting the computer off and restarting by pressing the front power button.

To press the switch, use the nylon probe tool (Apple part number 922-5065).

With the computer powered up, press the SYS_RST switch located in the upper right-hand corner of the logic board.

This switch can be used to determine if a computer that won't consistently boot from a cold start has power supply issues. Mac Pro (Early 2008) has a system reset switch on the logic board that may be used to restart the system while it is powered up. You may need to remove a PCI Express card to have access to the battery. Remove the battery for at least 20 seconds.If the computer is experiencing an issue booting, resetting the RTC may resolve it. The Real Time Clock (RTC) is a chip on the logic board that controls the date and time functions of the computer. Note: Unlike the logic board in earlier Mac Pro models, the logic board in the Mac Pro (Early 2008) computer does not include an SMC reset switch. Press the power button to start up the computer.Plug the power cord back in, making sure the power button is not being pressed at the time.

From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).

If the computer still exhibits these types of issues after you've restarted the computer, try resetting the SMC by removing AC power: Resetting the SMC can resolve some computer issues such as not starting up, not displaying video, sleep issues, fan noise issues, and so forth.

Force Shut Down (press the power button for 10 seconds).

If the computer isn't responding, perform these steps one at a time, in the following order, until the issue has been resolved: Resetting the SMC will not resolve issues in which the computer is unresponsive-in these situations, restarting the computer will generally suffice. Note that resetting the SMC does not reset the PRAM. It is also recommended that the SMC be reset after a logic board, ambient board, or ambient board cable is replaced as part of a repair.

Handling system resets from various commands.

Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth.

The SMC controls several functions, including:

If the computer is experiencing any power issue, resetting the SMC may resolve it. The System Management Controller (SMC) is a chip on the logic board that controls all power functions for the computer.
